| Abstract: |
| This paper takes a fluorspar and barite ore in Yunnan as the research object. The ore is high in fluorspar and barite. The ore contains fluorspar which grade is 33.46% and barite which grade is 52.73%. It is difficult to separate fluorspar and barite because of the similar floatability, so it is significant to utilize the mineral resources with beneficiation tests. The bulk flotation and separate flotation processes were adopted in the experiment. The bulk flotation was carried out under the conditions: the grinding fineness of -0.074mm accounted for 80%, the pH value is adjusted to 9, using sodium silicate as inhibitor and sodium oleate as collector. The aim of bulk flotation is pre-concentrating of the aimedSminerals and discardingStailings. TheSseparatingSflotationSis tested by inhibiting barite and floating fluorspar. The separating flotation which separating fluorspar and barite was carried out under the conditions: the pH value is adjusted to 6, using sodium silicate, aluminum sulfate and tanninSextract as inhibitor, using sodium oleate as collector. After the closed circuit flotation experiments, the grade of fluorite concentrate is 96.13% and the recovery rate is 88.74%, and the grade of barite concentrate is 87.65%, and the recovery rate is 97.78%. |
